Well another scrapped part, just like the others, off in the Y axis. I don't know if it will make a difference but I picked up to new steppers today. Tomorrow I will see if this solves the problem, if it doesn't then I'll start to look elsewhere. One thing that I discovered by accident is last night I accidently left my machine on, this morning I checked the temperature of the stepper motors, the x motor was 96 degrees, the y was 126 degrees. I didn't even think of checking the z motor. It only reaches 96 degrees when running.
Hood, what IPM do you cut with on your BP?
